HUD Speed Announcements go crazy since last update

[Glendathu]

Is it just me ? I couldn't find anything about that here. 

Since the last update the HUD Speed announcements in the upper right corner no longer appear and then vanish at the speed sign, but instead they are appearing and vanishing in a fast loop over and over again until the speed sign. That's rather annoying because I can barely read the distance to the speed restriction.

I found out this does not affect all locos, only:

Pendolino
Impuls
Traxx
Dragon
